I want to say that I saw that coming...but I totally didn't.
I mean, I had a feeling sometime during the middle of the story, but then I thought, "nah, he wouldn't." but then he DID and I was just like, "Holy shit!!"

So, in shorter words, I loved it. The ending was perfect! The way that it happened so sudden, but not so much so that it felt like it happened out of nowhere.
